Well I've been having troubles with my car, as some of you know, since summer started. It would never throw a code, it just runs like crap, and I knew BEFORE it dynoed 150hp that it was down on power. Now i KNOW its down on power. I think my problem is the fuel pump. As far as i know, its what came in the car in 94...140,000 miles on it . I've been reading on what could be wrong, seems like everything i check is fine. Well I was reading last night, and read that if you have a bad fuel pump, that it sometimes wont start, which is what i get a lot. Andy was saying that if the pump isnt strong enough to prime the system when you turn the key on, that it wont start, might take a couple more tries. Also, my car will cut out in the high RPM's, and i also read that the motor will try to cut out if its not getting enough fuel, which also could be the pump. It also revs slow, and has no "get up" to it. My dad's 95 V6 stang seems to have more "pep" to it than my car.

Anyways, my car is going into the shop on friday, a good guy that knows his fords. He's gonna hopefully let me know whats wrong, in 2 weeks i'm going to the NMRA's so i'm hoping its fixed by then. If its just the fuel pump i'll order a 255LPH and be done with it. hopefully thats ALL it is. Oh yea...and a new set of tires

You NEED to get/borrow/rent a mechanical fuel pressure gauge to check. If its the fuel pump you'll probbaly see a loss of fuel pressure or see it drop under load.

i know man, i just cant see myself paying $40 at autozone for the FP gauge. They wont rent it. The guy i'm taking it to will be able to tell if the pressure is off and stuff. I really hope that a bad FP is all it is. Its progressivly getting worse, which leads me to believe its the FP. It also makes a lot of noise.

Yeah then take it to a trusty shop and have him put a mechanical fuel pressure gauge tester on. On a stock car like yours i'd say you'll see around 30-32psi at idle. Look for 39psi at full throttle.

How old is your fuel filter?

I am with Mike - a FP gauge is a great investment. You will use it time and time again.

In any case, good luck.

Metco liquid filled gauge it's cheaper than BBK. I just put mine on a day ago it works like a charm. I also have a 10% sale code you can use if your going to buy it.
